Arecent survey showed that 102 adults out of a sample of 400 do not like cold weather. however, 115 of those studied said that they had interest in taking skiing lessons. based on this sample, if an adult is chosen at random, what is the probability that he or she has no desire to take skiing lessons? express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
